This should be done before the young scatter and would be more effective 

 if the brush was dipped frequently in kerosene emulsion or other insecti- 

 cide. Prof. C. M. Weed states that this pest can be fought with a con- 

 siderable degree of success by washing it from the tree with a stream 

 from a hose. Where there is a good head of water this might prove the 

 best method of controlling the pest. Otherwise, infested trees must be 

 headed in and sprayed with a lo to 12 per cent kerosene emulsion at the 

 time the young appear.

Black-banded scale 



Eulccaniu)]! nigrofasciatuni Perg. 



A small, hemispheric, reddish, black marked scale insect may be met with in large 

 numbers on the underside of branches of maple and of some other trees. 



This small species is somewhat common and quite injurious to the soft 

 and sugar maples in certain cities and villages of New York State. It was 

 brought to the notice of the late Dr Lintner several years ago, because 

 of its remarkable abundance on sugar maples at Poughkeepsie, and the 

 writer has since had his attention called to its presence in several localities. 

 It is now a very common and destructive pest of both soft and sugar maples 

 in the city of Albany. Mr Pergande, its describer,- states that he has 

 known the insect since 1872, wdien it was discovered on peachtrees at Hills- 

 boro Mo., and that since then it has increased steadily and has been gradu- 

 ally spreading over the peach orchards of the INIiddle, Southern and 

 Eastern States. He seems inclined to consider its original home as being 

 in the region south of New York and north of the Potomac river, and he 

 believes that it has been distributed from this region by means of cuttings 

 and young trees and to a lesser degree through the agency of birds ajid 

 insects.
